App Store is the only official app store. If you don't know how to put it on the shelves, you can use the third-party developer service platform to put it on the shelves. In the case of applying the specifications, it can be put on the shelves in three days.
However, Apple's review has always been relatively strict. It's best to make sure that your application has no violations or sensitive information before it is put on the shelves. Otherwise, the submission will not pass, but it will waste time.
Step 2 make an apple signature
This is a common method for many apps that have not been put on the shelves, or apps that need internal testing to be put on the shelves. Make an apple signature for the app and you can publish it without putting it on the shelf.
Apple signature can be divided into enterprise signature, super signature and tf signature.
Enterprise signature uses enterprise developer account, which is weak in stability, but cheap, and there is no restriction on APP installation.
Super signature uses personal developer account, which is relatively stable, but personal developer account can only add 100 udid. Therefore, it is also more expensive, and it is charged according to the download volume.
TF signature is actually the TF on the shelf. It is officially recognized by Apple, and it is considered as a beta app store. Its review is not as strict as the App Store. As long as it can be put on the shelves, the risk is very small and it will basically not be signed.
